located on the data plate on the rear panel of the
individual machines. Consult local authorities for
information regarding plumbing and electrical codes in
your area. Remove the left and right side panels for
power hook-up.
Note: All SaniServ machines should have their
own dedicated circuits to prevent low voltage
conditions caused by other operating equipment.

temperature of approximately 125°F. (52°C.) to 130°F.
(55°C.). For best cleaning results select a concentrated
anti-bacterial dishwashing detergent containing
biodegradable anionic and nonionic surfactants. Avoid
detergents containing phosphates. DO NOT use an
abrasive detergent on any part of the dispenser.
DO NOT USE HOT WATER.
DOING SO MAY DAMAGE THE MACHINE.

pan with the cleaning solution. Clean the mix pan
thoroughly with a brush as the solution drains into the
freezing cylinders. Clean the mix inlet tubes with the
brush provided.
4. Set the control switch to the “CLEANOUT” position
and agitate for approximately 1 to 2 minutes and then
drain the water by pulling down on the spigot handle
After the unit is empty, set each control switch to the
“OFF” position.

REMOVE ANY O-RINGS FROM THIS MACHINE.
SHARP OBJECTS WILL DAMAGE THE O-RINGS.
5. Remove the front plate by turning the black plastic
knobs in a counterclockwise direction (Fig. 6).
Disassemble the front plate in the following manner:
a. Remove the faspin and spigot handle.
b. Remove the front plate o-ring.
c. With the spigot handle removed, push the spigot
plunger out the top of the front plate and remove all
lubricant from the spigot plunger.
d. Remove the o-rings from the spigot plunger by
grasping the part with one hand and with a dry
cloth in the other hand, squeeze the o-ring upward.
When a loop is formed, grasp the o-ring with the
other hand and roll it out of its groove and off the
spigot plunger (Fig. 7).

c. In a third partition, sanitizing rinse solution which
will produce a 200 parts per million (PPM) Chlorine
residual or whatever Chlorine residual is required by
your Local Health Authority.
13. Use the brushes to clean all holes and ports in the
parts (Fig. 11).
DO NOT use an abrasive detergent
14. After thoroughly washing the parts in the detergent
solution, rinse them in the clear rinse water. Place the
parts in the sanitizing solution for at least five minutes or
whatever your Local Health Authority requires, and then
air dry the parts before for assembly and lubrication.
DO NOT ALLOW THE PARTS TO SOAK IN
SANITIZER FOR SEVERAL HOURS.
DO NOT WIPE THE PARTS DRY - AIR DRY ONLY.
15. The remainder of the machine including the mix pan
and freezing cylinder must be cleaned in place using a
mild detergent solution followed by a clear rinse. Clean
the exterior with a damp cloth.
DO NOT use an abrasive cleaner on the exterior of the
machine or on any of the panels (guards).
WHEN CLEANING THE MACHINE, DO NOT ALLOW
EXCESSIVE AMOUNTS OF WATER AROUND ANY
ELECTRICALLY OPERATED COMPONENTS OF THE
